To (LZZ whom it may concern:

Be it known that I, ROBERT A. Ronnson, a citizen of the United States ofAmerica, and

a resident of Dixon, in the county of Lee and State of Illinois, haveinvented certain new and useful Improvements in Automatic Pianos, ofwhich the following is a specification.

This application is a division of my application filed September 11,1905, Serial Number 277,814.

This invention relates to that class of automatic piano players in whicha pneumatically actuated playing mechanism is controlled by a travelingperforated music sheet or like controlling means; and the presentimprovement has for its object to provide a simple and compactstructural formation and combination of parts adapting the automaticplaying mechanism for convenient application to an ordinary uprightpiano, without requiring any change in the form, dimensions, orappearance of the same, and with which the operation of the self-playingmechanism is rendered easy and eflicient, all as will hereinafter morefully appear and be more particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a transverse sectionalelevation of an upright piano, having the present improvements applied.Fig. 2 is an. enlarged fragmentary front elevation of the upper part ofthe piano, illustrating the arrangement of the tracker board, musicsheet carrying mechanism, etc.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawin s:1 represents the rear frame of an uprightpiano, upon. which the sound board, and string plate are mounted in thecustomary manner. Such rear frame is inclosed in the usual outer pianocasing which in detail comprises the usual key table 2, and itssuperposed desk front 3; stationary cap board 4; hinged cover 5; upperfront board 6, screen board 7; lower molding rail 8, and bottom board 9,as well as the other minor parts usual to an upright piano.

10 are the action keys mounted in any usual manner on the key table 2,and having operative connectionwith the usual piano action 11.; suchaction comprising the usual series of hammers, their throwing jacks,rockers, back catch springs, trip devices,

in the operation of the piano.

martingales, and lift bars, as well as the con- 5 5 necting pivots forsaid parts.

12 is the manually actuated exhaust pump of the pneumatic playingmechanism, ar ranged in the lower part of the piano casing immediatelyto the rear of the screen. board 7, of such casing, as shown in Fig. 1.Such pump may be of any usual construction, the bellows form shown beingpreferred, in that it can be arranged for convenient actuation by thepedal lever hereinafter described.

13 is the collapsible exhaust equalizing or accumulating chamber of anyusual form communicating with the exhaust pump, and adapted to equalizethe exhaust action of such pump, or a pair of such pumps when two areused to create the exhaust action of the playing mechanism.

14 is the exhaust chest or chamber of the playing mechanism,connnunicating with the upper end of the exhaust equalizing chamberaforesaid, and arranged in an upright position immediately above saidchamber, and behind the screen board 7, in the preferred arrangement ofparts illustrated in Fig. 1 of the drawings.

15 are the primary prieumatics arranged in the exhaust chest 14, andadapted for actuation by the music or controlling sheet acting inconjunction with the individual openings of the tracker bar, ashereinafter more fully described.

16 is a shelf, having a series of air conduits, and extending forwardlyfrom the upper end of exhaust chest or chamber 14; such air conduitshelf being arranged immediately beneath the key table 2, and preferablya ttached to the underside of the same.

17 are the series of operating or motor pneumatics which. actuate theaction keys 10 In the present construction such motor pneumatics havetheir lower and fixed members mounted rigidly upon forward extensions atthe front side of the air conduit shelf 16, while the margin bodies oftheir movable members are connected in a direct manner with the actionkeys by vertical pull connections 18, preferably of a pliable material,such as leather, and so that in the ordinary actuation of the actionkeys by a player the pull connections are free to yield and not offerany impediment to the normal and free movement of said action keys. Bythe aforesaid arrange- ICC) ment of parts, the points at which thevertical pull connections 18 are attached to the action keys correspondwith the normal points at which the keys are struck by the player in theactuation of the instrument. The result of such arrangement is that thetone produced in the automatic operation of the instrun'ient veryclosely approaches the tone produced in an ordinary actuation.

With a view to afford a compact arrangement of parts, the fixed memberof each motor pneumatic is arranged in an inclined direction upon theforward extension of the air conduit shelf 16, as shown in Figs. 1 and2, so that when. each. movable member is in any expanded condition itwill have a horizontal position immediately beneath the key table 2approximately parallel to the action keys, so that the motor pneumaticwill occupy a minimum amount of vertical space beneath said key table.

19 is a depending bar at the front end of the key table adapted toconceal the forward ends of the motor pneumatics from view, and protectthem.

20 are vertical orifices in the key table from the passage of thevertical pull connections aforesaid.

The arrangement of the operating or motor pneumatics and theirconnection to the action keys constitutes the subject matter ofmy application, filed September 11th, 1905, Serial Number 277 ,814hereinbefore referred. to.

2]. is the carrying frame of the tracker board, take up and rewindrolls, and their usual accessories. In the present improvement such.frame is arranged in the upper portion of the pianocasing to the rear ofthe upper front board 6, of such casing, and is made verticallyadjustable so that when the hinged cover 5 is thrown back, the saidframe can be raised above the top of the piano in a convenient positionto display to the operator the music or controlling sheet as it passesover the tracker board. The vertical adjustment of said frame isattained by mechanism hereinafter described.

22 is the tracker board of any usual construction carried by the frame2]. Such tracker board will have the usual series of passages which. inthe present construction are connected by a series of flexible pipes orducts 23, with a corresponding series of passages in the end trunks241-, hereinafter described, the series of passages in said end trunksconnecting in turn by pipes or ducts 25 with a corresponding series ofpassages in the exhaust chest 14, which contain the series of primarypneumatics before referred to.

26 is the take up roll, and 27 the rewind. roll for the controllingsheet 28. Such rolls are arranged at opposite sides of the tracker boardand are adapted to guide and move the controlling sheet 28 over theopenings or passages in said tracker board, as usual in the present typeof self playing pianos, and to this end a suitable spring or other usualmotor, not shown, will be connected to a pulley 29, carried by the frame21 and haveoperative connections with said rolls. I n the preferredconstruction of the said rolls, as shown in Fig. 2 of the drawings, theholding enters 30, at the inner ends of the rolls 26 and 27, are adaptedto yield, under the influence of the winged spring 31, to permit of alimited longi udinal adjustment of said rolls in effecting an adjustmentof the controlling sheet28 with relation to the tracker board.

32 is a yoke member having an adjustment in the frame 21 longitudinallywith the rolls, and adapted to afford bearings for the operating shafts33 and 3 1- of said rolls; such yokes are adapted to have endwisebearing against the adjacent ends of the rolls so as to resist the endthrust of the same due to the spring 3]. before described.

35 is an adjusting screw and nut by which adjustment is imparted to theyoke 32 longitudinally with the rolls.

The specific mechanism above described for effecting a lateral ortransposing adj ustment of the rolls and music sheet above described,constitutes the subject matter of a companion. divisional application,of even date herewith, Serial Number 328,402.

36 are depending rack bars at the respective ends of the frame 2] movingin suitable guides formed in the board or rail 37, hereinafter referredto, so that said bars will guide said frame in a vertical direction.

33 is a spring roll journaled on the board or rail. 37, and providedwith pinions 39, engaging the aforesaid rack bars 36, the arrangementbeing such that the spring tension of the said roll will counterbalancethe weight of the frame 21 and the parts mounted thereon, so that thesaid fran'le will remain in. any vertical adjustment at which it may beplaced by the operator.

The end trunks 24, before referred to, are located at opposite ends ofthe interior of the piano casing and at opposite sides of the trackerboard, and. are detachably secured to the top of side cheeks 40, fixedin the interior of the piano casing, and provided. with a series ofpassages corresponding with the series of passages in said end trunks,so that the passages in both parts will register when in proper relativeposition. The series of passages in said cheeks communicate in turn withthe series of pipes or ducts 25 before referred. to.

In the preferred form of the present in vention, as illustrated in Fig.2, the end trunks 24 are carried by 'he board or rail -17, heretoforereferred to, and the arrangement is such that said trunks 24, the board37, the tracker board, the take up and rewind rolls, and gearing withthe pulley 29 which is connected to the motor, can be removed as an llOentirety from the piano for tuning and like purposes.

41 are vertical screws by which the trunks 24. are secured to the cheeks40, in the detachable manner above set forth.

50 is the pedal lever for actuating the exhaust pump 12 of the pumpingn'ieehanism. In the present construction,such lever is provided with adepending arm 51 intermediate of its length by which it is pivoted tothe bottom board 9 of the piano casing by suitable pivot brackets, asshown in Fig. 1. The forward end of said lever projects through thebottom front rail 52 of the piano casing for operative engagement by thefoot of the operator, while the rear end of such lever is formed with anupward and angular extension. 53, the free end of which operativelyconnected by a link 54 to the movable memher of the exhaust pump 12, asshown. Such construction is adapted to afford a very compact andefficient arrangement of parts wl'iereby the operation of the exhaustpump can be effected in an easy and convei'iient manner, and constitutesthe subject matter of a companion divisional. application, of even dateherewith, Serial Number 328,403.
